Electrical Nature of Matter Grade Nine Science. Question to Ponder What happens when you rub a balloon against your hair? Does this action create electric.

Electricity. Electrical Charge and Forces  Electrical charge is the property that causes protons and electrons to attract or repel one another.  There.

Electricity and Magnetism – Chapter 4

Electrical Charge is all about ELECTRONS! A gain of electrons causes a negative charge. A loss of electrons causes a positive charge.

 What are the parts of an atom?  Which particles are  positively charged?  negative?  neutral?  What are the two Laws of Electrical Charge?  Opposites.

Static Electricity.  A buildup of electric charge on an object.  Does not flow through wires  “Static” means “not moving”.  May “jump” from one object.

Electric charge is a fundamental property of matter, like mass. Electric charge is a fundamental property of matter, like mass. Objects are either positive,

Clues 1.This rubbing action applies a force which makes insulators become charged. 2.This is what happens when like (the same) charges are close.

What is Static Electricity? Section Recall… All matter is made up of atoms –Protons – positive charge in nucleus –Neutrons – neutral charge in nucleus.

7.2 ELECTRIC FORCE BC Science 9: p Force A force is a push or a pull. – Eg. Shooting a basketball or pulling a wagon. Forces that are directly.

By Carla Bridges.  Investigate and describe that without touching them, material that has been electrically charged pulls all other materials.

Balloon and Sweater Activity. Task Description A balloon will be rubbed on a sweater as shown. The balloon will then be brought near the sweater and released.

Electric Charge & Force Static Electricity. Electric Charge An electrical property of matter that creates a force between objects Ex. When you get shocked.

1 Day 1: Static Electricity 2 Electricity exists in nature and comes from the electrons in atoms Most objects tend to be.

 Force: a push or a pull  Shooting a basketball  pushing the ball  Pulling a desk across a room  Contact Forces: forces that have an effect ONLY.

What is Induction? Charging by induction is where a charged object causes electrons to move inside another object, without them touching. No charges move.

Topic Static electricity Level For students aged 11-16 Outcomes Students are able to use models to describe and explain static electricity Instructions for teachers: show students what happens when you rub a balloon against hair and pose the question ‘what is happening to the hair?’. Allow students to think, pair and share. Students then copy down the table on slide 3 and move around the room using clues 1,2 and 3 to complete the table. Finally the class comes together to discuss what is actually happening and students do the writing task. To really challenge students you can ask them to explain how the balloon ‘sticks’ to the wall. You may want to introduce atomic structure before you start teaching this lesson. www.thescienceteacher.co.uk | resources for science teachers who like to think

What is happening to the hair in this picture? Think | Pair | Share

Gathering your information Clue What does the model tell you about what happened to the hair? Model 1 Model 2 Model 3

Clue 1! + + + - - - + + + - - - + + + - + + + - - - Before rubbing the hair with the balloon After rubbing the hair with the balloon Hair Balloon Hair Balloon + + + - - - + + + - - - + + + - + + + - - - Think! What has changed? What caused this change?

After rubbing the hair with the balloon Clue 2! After rubbing the hair with the balloon Balloon Hair Balloon Hair + + + - - - + + + - + + + - - - + + + - Think! Count the charges

After rubbing the hair with the balloon Clue 3! After rubbing the hair with the balloon Hair Hair Hair + + + + Think! Why are there only + symbols shown in this diagram?

Use the models in clues 1, 2 and 3 to help you explain what is happening to the hair in this picture. Key words: Charge Friction Transfer Electrons Repel Attract Think! Why would this not happen if the ladies arms were made of metal?
